Deduction of Electron Density Profile Information from a Single Chord Interferometry on KSTAR

摘要

Local electron density was deduced from the line integrated density measured by a millimeter-wave interferometer system. The estimated value is consistent with the measured value under the imposed profile assumption when the plasma is near the mid-plane. Additional constraints were imposed to ameliorate the discrepancy caused by the drift of the plasma position from the mid-plane.
